摘要

Mixed convection due to buoyant and centrifugal forces in the crucible of a Czochralski aparatus has a significant effect on the quality and stability of growing oxide single crystals. Thus, the present investigation is concerned with the time-dependent and three-dimensional simulation of the flow and heat transfer in an oxide melt with a rotating crystal for a fundamentla understanding of mixed convection and its effect on the surface waves. Based on an efficient block-structured finite-volume Navier-Stokes solver, quasi-direct numerical simulations (quais-DNS) were carried out.
